Singapore’s 2015 Infocomm budget using hierarchical Google charts

Google charts now supports hierarchicaltreemaps. You can put together a treemap without any programming. Here is a good tutorial on creating a treemap using Google charts. Here is my treemap of the Singapore 2015 Communications and Information development expenditure. I’ve created a top level map of the interesting (not drop dead boring) ministries. You can click on the Communications and Information value in the lower right of the chart to drill down. I don’t think there is any other free visualization package which allows the capability to drill down charts without programming.

Note that these charts have limited capability for customization. If you want to customize the charts, you will need to use javascript.
